This application claims the benefit of priority of Israel PatentApplication No. 279030 filed on 26 Nov. 2020 and of Israel PatentApplication No. 287212 filed 12 Oct. 2021, the contents of which areincorporated herein by reference in their entirety.

FIELD AND BACKGROUND OF THE INVENTION

The present invention, in some embodiments thereof, relates to a wallfor tiling and enclosing a space, and more particularly but notexclusively to a way of making a false wall inside a building, forexample for enclosing plant, pipes and plumbing installations such as atoilet cistern.

Enclosure of spaces inside a building typically involves building adrywall construction around the space, say using plasterboard. Likewise,enclosing of a built-in toilet cisterns typically require building adrywall construction around the toilet cistern. The drywall constructionprovides a surface that can be cladded with tiles, e.g. ceramic tiles.When constructing the drywall, a construction worker is required to formdedicated openings to provide access to the toilet flushing actuator,the waste water pipe, the inlet water pile and the pair of barsextending out from the built-in toilet cistern for supporting the toiletseat. The toilet seat and flushing actuator cover may be installed afterthe drywall construction is formed with the dedicated openings and iscladded with the tiles. The drywall construction may be partially filledwith cement to structurally reinforce the portion of the drywall thatengages the toilet seat when installed.

French Patent No. 3037978, entitled “Sanitary toilet kit protectedagainst fires,” discloses a sanitary unit of fire-protected toilet witha wall which has an anterior side and a posterior side turned towards asanitary space and which is further configured for the junction with atoilet. It has a flushing water passage opening for the passage of aflushing water pipe, a waste water opening, an actuating opening for thepassage and/or the housing of an actuating element for a recessed flushtank placed behind the wall in the sanitary space and at least oneprimary element of protection against the fires configured to close atleast one passage opening. The wall has at least one gypsum board, atleast one secondary fire protection element being provided on the rearside of the wall around at least one passage opening, isolating amarginal area of the passage opening against the effects of heat.

The reinforcementmay be an additional layer of material, optionally positioned on aninner face of cover 100.

Reference is now made to FIG. 3 showing an exploded view of the examplecover being assembled and FIG. 4 showing the example cover whenassembled on the built-in cistern, both in accordance with some exampleembodiments. According to some example embodiments, a cover 100 isconfigured to cover a built-in toilet cistern 50 that is fixed against abackup wall 10. In some example embodiments, actuating actuator opening120 is sized and positioned to align with actuator of built-in toiletcistern 50 and receive an actuator cover or handle after fullinstallation of the toilet. Similarly, water opening 110 is sized andpositioned to align with inlet water pipe 40 and waste water pipe 30 andprovide connecting inlet water pipe 40 and waste water pipe 30 to atoilet seat. Optionally and preferably, water opening 110 is also sizedand positioned to align with supporting structure 60 so that supportingstructure 60 can penetrate through water opening 110. Typically,supporting structure 60 is a pair of bars for supporting a weight of thetoilet seat. The bars may be supported at their far end by a horizontalbar 61 that extends across the back of the cistern, and at the front endby supporting ribs of the reinforcement structure 140 of the cover toprovide a stable support for the toilet bowl. Although, a single wateropening 110 is shown for providing access for each of inlet water pipe40, waste water pipe 30 and supporting structure 60, separate openingsfor some or each of the components are used in the embodiments below.

According to some example embodiments, cover 100 is sized to extend tothe floor 11 or substantially near floor 11. Opening 145 in bottomfacing side panel 106 provides supporting cover 100 against backup wall10 with floor mounting frame 70 extending therethrough. In some exampleembodiments, a plurality of screws 135 are used to fix cover 100 againstwall 10. According to some example embodiments, once cover 100 is fixedagainst wall 10, cover 100 may be cladded with tiles, e.g. ceramictiles. Optionally and preferably, cover 100 is sized and shaped toreplace a need to build a drywall around the built-in toilet cistern andto provide a suitable surface for cladding or for covering with mortaror plaster or ceramic tiles and the like, herein referred to as a wallfinish. Optionally, a drywall construction may be built around cover100. Optionally, a drywall may fixed against cover 100. Thus the wallfinish effectively encloses the cistern behind a false wall, providingaesthetic enhancement to the bathroom environment. According to someexample embodiments, cover 100 is sized to provide a full constructionaround built-in toilet cistern with pre-fabricated openings (actuatoropening 120 and water opening 130) at known locations based on the knownstandard of built-in toilet cisterns 50.

Reference is made to FIGS. 5A-5G, which are a top front perspectiveview, a front view, a rear view, a bottom rear perspective view, a topview, a side view and a bottom view respectively, of a cover accordingto the present embodiments. As before, cover 100 is an open box likeenclosure with a rectangular shaped front panel 102 and four side panels104.

As above, front panel 102 includes an inlet water opening 110, an outletwater opening 111, and an actuator opening 120. Inlet water opening 110,outlet water opening 111, and actuator opening 120 provide access tocomponents of the built-in toilet cistern, e.g. inlet water pipe, wastewater pipe, and flushing actuator and holes 160 may allow supportstructure 60 from the cistern to extend through and support the toiletseat. A bottom facing opening 145 may allow a floor mounting stand ofthe built-in toilet cistern to extend.

Some or all of front panel 102 and/or side panels 104 are formed with agrid of through going holes 112. Grid 112 may be at least partiallyfilled with mortar during cladding. Optionally, grid 112 on front panel102 may have larger openings as compared to grid 112 on side panels 104.Optionally, grid structure 112 provides improved mechanical fixation ofthe cladding elements against cover 100. Alternatively or additionally,at least a portion of front panel 102 and/or side panels 104 may beformed with frictional protrusions that may also provide improvedmechanical fixation of the mortar and cladding elements, e.g. ceramictiles, against cover 100.

In the grid 112, through-going holes are defined between surroundingbars of the grid. In embodiments, selected ones of the bar sectionsbetween two neighboring holes are recessed. The recessed bar surroundedby non-recessed bars forms a firmer foothold for cement. Typically therecessed bars are selected in a regular pattern, and the pattern isselected on the basis of standard sized cladding tiles, so that eachtile of the cladding has a given number of recessed bars to ensureeffective support.

In one embodiment, a prelocated cistern is already in position, andcover 100 is provided to place around the cistern. Once the cover isfixed in position, it may be covered in mortar or plasterboard or tiles,including ceramic tiles, so that the cistern is hidden behind a falsewall.

In another embodiment, the cistern is provided together with the cover100. In such a case the cistern is plumbed into position and the cover100 is placed around and over and covered in mortar or plasterboard asbefore to provide a wall finish.

In a yet further embodiment, a plaster or other wall may be provided ona second side, so that the cover is only needed to conceal from aboveand on one side. Accordingly, the wall finish applied to the cover maymerge into the plaster or other wall finish of the second wall. Thus thecover encases the cistern against the back up wall and the second wall.In any event, whether or not there is a second wall present, the coverencases the cistern against at least the back-up wall.
